摘要Lycodon (Boie,1826) is a genus of colubrid snakes widely distributed in south,south-east and east Asia comprising 84 species with 22 reported in China.In this study,we identify a unique Lycodon specimen (voucher No.ANU20230057) from Yingjiang County,Yunnan Province,China.A phylogenetic analysis using mitochondrial cytochrome b (Cyt b),showed that this specimen formed a monophyletic clade with high nodal supports (BPP=1.00;BS=100) with a specimen of Lycodon jara,a colubrid species mainly distributed in the northern and northeastern region of south Asia.Morphological comparisons also showed that this specimen belongs to L.jara.This discovery confirms the distribution of L.jara in China and expands the range of this species to the south edge of Gaoligong Mountains,and provides the first detailed morphological description of L.jara from China thus increasing the number of Lycodon species in China to 23.
